There apparently is an issue with the 14900K and even in some cases the 13900K with the default settings on most motherboards. When I started having issues, the first thing I did was reset all of the settings on my motherboard to the defaults hoping that would cure the issue. I even replaced the ASUS motherboard with an MSI motherboard, but the issue persisted. I spent many, many hours on the phone with various tech support centers to try to find a solution, as well as just trying everything I could to ensure there was not a faulty piece of hardware on the computer. It was extremely frustrating.
Yesterday, I was reading some gamer forums since gamers tend to spend a lot of time tweaking their systems. I found a thread that dealt with crashes with the 14900K i9 CPU. They were having crashes in several games when the GPU (graphics card) kicked in with a high load on the power, especially when an RTX 4090 card was in use. They had found that the default settings for the Performance Active-Core Ratio (P-Core) on most motherboards was set to around 57x. They suggested backing that down to 54x to resolve the issue using the Intel Extreme Tuning Utility App.
I downloaded the software and changed each P-Core from 57x to 54x and rebooted. After about 6 hours of continuous use and many refreshes of the plot line elevations, I have not had any crashes. I hope this helps someone who might be having similar issues, so they don't spend an exhaustive number of hours trying to pinpoint a solution like I did.
You have at least one wall that is marked "No Room Definition" in the wall DBX. Just select all of the walls and open the dialog. There will be a dash next to that setting. Click it until the box is empty, and you should be good.
